Add a skill for reviewing and cleaning up R package code against the tidyverse style guide, separating mechanical formatting from behavior-sensitive refactors and deferring to the package's existing conventions.

Frontmatter (name, description, author/version/license metadata) is administrative and the description is reported separately, so it should not count toward the skill budget. Strip only the frontmatter block with a regex; python-frontmatter's .content also drops the leading blank line and trailing newline, which skewed line counts by 2.

Purpose
Adds a new
r-tidyverse-styleskill underr-lib/for reviewing and cleaning up R package code against the tidyverse style guide, with a focus on code largely written by LLMs. It separates mechanical formatting from behavior-sensitive refactors: formatting scoped files comes first, while pipe conversions, evaluation-order tweaks, public renames, or error-text changes are proposed separately and only applied when the user has authorized that scope. It also defers to the package's established conventions over the tidyverse guide unless a migration is requested.Use cases
Testing
./count-skill-tokens.py r-lib/r-tidyverse-stylepasses with no warnings (full output below)marketplace.jsonand both READMEscount-skill-tokens.pywas updated in this PR to exclude SKILL.md frontmatter (author/version/license metadata) from the line and token counts, since the description is already reported separatelyDependencies
No required dependencies. The skill documents optional tooling: Air for scoped formatting, and
